' Application filed m 27, 1899.

-Be it known that I, JOHN JAMES GREEN- OUGH, a citizen of the United States, residing in .Washington, District of Columbia, have invented certain new and useful Improvements in Breech-Loading Firearms, of which. the following is a description illustrated by.

, View of the breech-block and lever detached;

Fig. 4, a cross-section of the breech on the dotted line an moi Fig. 2 with the breech-block down. Fig. is a longitudinal section show- 7 ing the shell-extractor andits connections.

' ceive a loaded, one.

The same parts are designated by the same letters in all the figures.

The frame a is a metal piece in which. the gun-barrel g is affixed and so shaped as to leave a space a in rear of the open end of the barrel, forming a chamber to receive the breech-block that closes the end of the barrel and opens ,to-remove the empty shell and re- The front face ofthe chamber 02' is perpendicular to the open end of the here. The opposite face is concave on a curve concentric with the pivot b hereinafter named. The sides of the chamber are parallel, and in it the breech-block slides,-

' filling it tightly when closed, as seen in Fig.

'1. The breech-block b is a piano-convex wedge, of metal, with parallel sides, that fits into and fills the chamber. a and covers the rear end of the bore, against which it is wedged tightly. This breech-block is afiixed permanently to a metal bar or lever 11. I prefer connecting them by a dovetail joint and inserting a keyy or set-screw, by which the block b can be adjusted in case of expansion by heat in firing. 'The lever b is "pivoted beneath the barrel at Win a groove in. the breech-frame a. It extends backward .beyond the breech-block and trigger-guard, that may be attached to and form a part of it as a brace. The rear end of this lever is Serial 1%, veassifnifiiano furnished with a spring-bolt 0, that looks it to the frame a. Athumb-piece c, of convenient shape, is pivoted to the lever, which when forced down frees the spring-bolt 0 and throws out the lever b by a single impulse.

a thumb-piece (not shown in the drawings) to cook it independent of the bridle, the trigger tion for either rim or center fire. They are pivoted in the frame a, properly recessed to receive them. A link or bridle h is used to cock the hammer automatically. It is joined .by a pivot-pin to the lever at its lower end at k and extends up to a pin 2' on the hammer, as shown in Fig. 1.

When the parts are in cocked, ready to fire on pulling the trigger.

it parallel with the barrel. its rear end is iformed to fit under the rim of a shell and is Iss1) shaped as to permit the loaded shell to be readily inserted. The bar m'extends forward into a chamber in the frame over lover I). (See Fig. 5.) To actuate the extractor m, a togglejoint n is used, consisting of a long and a short arm, the latter being pivoted to the long one at its center and to the permanent frame a. On the forward end of the long arm there is acatch that when the lever b is closed engages with the extractor m, the arms being nearly in line with eachother.v The opposite end of the long arm is connected with a spring .5, affixed to the ieverb, so that when the 10 ver is thrown out the spring bears on the rear end of the long arm 'n, causing the catch on the opposite end to bear against the shellextractor, pressing it back and bringing the shell in contact with the breeclvblock, and

This bridle has a slot in it, preferably of curved form concentric with r The shell-extractoris represented at Fig.v

which can then' be readilyrretracteduby the insertion of a loaded shell or automatically byaspring. What I claim as my invention, and desire to secure by Letters Patent, is- I 1; A plano-convex wedge-shaped breechblock b' combined with the chamber a into slides and wed gejs as and ,for the pun poses specified. f I

2. In a breech-loading firearm a hammer and mai-nspring in a recess in rearof the breech-block as described, combined with alever of the second class by a pin-or projection on the side of the hammer and a link attached to the lever moving the hammer in conjunction with the breech-block as and for the purposes set forth in the description.

3. In a breech-loading firearm the combination of a hammer its.

4.
